Title: Production of a continuous moulded plastics strip
Inventor: MENZIN M
IPC: B29C48/35
Filed: 1970-05-14
Abstract: 1319511 Moulding piled sheets SOC POUR LA RECHERCHE ET LE DEVELOPPEMENT TECHNOLOGIQUE SA 14 May 1970 [14 May 1969] 21764/70 Heading B5A An article comprising a base member from which other members project, for example a strip having hook shaped piles and suitable for use in a releasable fastening, is made by injetting plastics material into a series of mould cavities formed between relatively slidable plates in contacting surface-to-surface relationship, the mould cavities intersecting one edge of the plates and being defined by a recess in one plate and the oppositely located area of the adjacent contacting plate. Base material is extruded on to the moulding surface formed by the aligned edges of the plates after injection and when the materials have set alternate plates are slid relative to their neighbours so as to expose the recesses and the projections formed therein, thereby facilitating removal of the article from the moulds. In the particular embodiment, a strip of plastics having hooked projections on one surface is moulded by extruding material on to the surface of a suitably configured drum. The configured surface of the drum is made up from a circular array of eight sections A-H of plates, each set comprising interleaved mould plates 29 having cavities 33 and 34 and flat spacer plates 30. The mould plates are held in a fixed position upon the drum between side discs 27 by cross pins 31 which engage in correspondingly dimensioned apertures 32 in the mould plates and oversized apertures 59 in the spacer plates whilst the spacer plates are carried by means of cross-bars 69 from plates 60 slidable over the outside of side discs 27. The plates 60 are radially reciprocable by means of cam rollers 63 mounted at their radially inner ends and movable around a central cam surface 65, the rollers being biased into contact with the cam surface by hydraulic cylinders 71. The cross-bars 69 pass through exactly sized apertures 70 in each spacer plate and through oversized cavities 84 in each mould plate. In operation, as the drum revolves each set of plates is brought to the extrusion head 46 where the associated rollers engage part 79 of the cam surface to move the spacer plates to their outermost positions flush with the mould plates. A first charge of material is injected through outlet 37 into the mould cavities and a second charge, forming the supporting layer of the strip, is extruded on to the surface of the plates through outlet 38. Further rotation then brings the rollers into different regions of the cam surface where the spacer plates are first pulled inwardly to free the hooks for subsequent removal of the strip over rollers 85 and are then moved outwardly in readiness for passage past the extrusion head again.

Title: Improvements in apparatus for cutting velveteens
IPC: D06C13/08
Filed: 1921-08-16
Abstract: 168,310. Canellas, D. Aug 28, 1920, [Convention date]. Void [Pitblished under Sect. 91 of the Act]. Pile, cutting; stop-motions.-The stem 22, Fig. 1, carrying the knife for cutting the loops of flat velveteen 50 is pivoted on an arm 18 and is acted upon by a spring 60, which tends to move the knife into an inoperative position. The knife is normally held in the cutting position shown by a tie-rod 27 connected to a rod 42 by an adjustable V-shaped. spring in a box 36, the other end of the rod 42 being connected through a clip 44, a sleeve 45, and a hooked spring 46 to a tooth 49 on an adjustable foot of the arm 18, the hook being kept in engagement with the tooth by a spring-controlled bell-crank lever 11, 12 acted upon by an arm 16 of the armature 15 of a permanent magnet or of an electromagnet 17 having a coil in which current is flowing constantly. When the knife meets with an abnormal resistance, the ends 32, 33 of the V-shaped spring are moved to turn a disc 34 and cause a rod 35 carried by the disc 34 to make contact with an adjustable terminal 40, and thus complete a circuit through a de-magnetizing coil of the magnet. The armature 15 then falls and releases the hook 48 of the spring 46 from engagement with the tooth 49, so that the spring 60 is free to swing the stem 22 to move the knife into the inoperative position. This movement may control means for stopping the travel of the velveteen. In a modification, the V-shaped spring is replaced by a spiral spring 65, Fig. 4, secured to the rod 42 and engaging a box 64, which is secured to the rod 27 and is connected by a link 66 to an arm 67 pivoted on the rod 42. When the knife encounters abnormal resistance, the arm 67 is moved to make contact with a stud 63 on a bracket 62 carried by the roa 42, thus completing the circuit in the de-magnetizing coil of the magnet as before.

Title: Improvements in and relating to modulation systems
IPC: H03C1/50
Filed: 1950-09-06
Abstract: 672,188. Modulating systems; phase modulation; valve generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 6, 1950 [Sept. 23, 1949], No. 21959/50. Classes 40 (v) and 40 (vi). An amplitude-modulated carrier-wave is derived by phase-modulating two low-power control waves of carrier frequency, and utilizing such waves to synchronize two high-power oscillators, the outputs of which are combined vectorially to produce a high-power-amplitudemodulated carrier wave. Fig. 2 shows the lowpower phase modulator, and Fig. 5 the highpower oscillators and the combining circuit. The low-power crystal-controlled source 1 feeds two pairs of valves 23, 24, of which two are fed in the same phase and the other two in quadrature phase, one leading and the other lagging, the phasing being provided by coupled tuned circuits 21, 22. A valve of each pair is amplitude-modulated in one sense by the cathode voltage of a valve 32, and the other valve of each pair in the opposite sense by the anode voltage, the valve 32 being excited by the modulating source 8. The push-pull outputs taken from each pair are phase-modulated waves which differ by 90 degrees in their mean position and shift their phase in opposite directions. These waves are amplified in stages 3, 6, Fig. 5, and are fed to quarter-wave stubs 54 on coaxial lines 53 coupled to the anode cavities of magnetrons 49 causing the highpower oscillations generated thereby to follow the phase modulation of the controlling input. The outputs of the magnetrons 49 are vectorially combined in a stage 10 comprising a transformer 60 fed from one magnetron and having a tuned secondary coil connected by a centre tapping to the tuned secondary coil of a transformer 62 fed from the other magnetron. In this way the output of one magnetron is combined with opposed phases of the output of the other to produce across the resistors 66, 67 a pair of amplitude-modulated waves, each of which rises to a maximum amplitude as the other falls to a minimum. One A.M. wave is dissipated in resistor 67 and the other fed to the aerial 72. A filter 68 may be arranged to transmit only one side-band 69 and a vestigial portion of the other to the aerial, the remaining portion 70 of the other side-band being dissipated at 71. The modulation characteristic of the system is of sinusoidal form, as shown at 75, Fig. 8, in which signal input is plotted as abscissµ, and carrier output as ordinates. When the system is used for television, the lower and comparatively straight portion of the characteristic is used for the picture signal 78 and the upper portion for the synchronizing signal 77. The synchronizing pulse input is made larger than normally, in order that at the carrier output the pulse may occupy the usual 25 per cent of the full range. The black components of the picture may be similarly emphasized. For audio signal transmission, the effects of the non- linear characteristic 75 may be overcome by suitable biasing of the phase-modulating valves 23, 24 and by predistortion of the audio signal input.

Abstract: 598,019. Statistical apparatus. BRITISH TABULATING MACHINE CO., Ltd. Aug. 28, 1945, No. 22169. Convention date, Aug. 31, 1944. [Class 106 (i)] [Also in Group XXXVII] A record-card controlled machine includes a pair of magnet coils adapted to be energized by impulses transmitted from the sensing stations of two record cards, and a contact-operating armature pivoted between the magnets and normally biassed to one of two positions in which it remains when both coils are energized. The group control designations of two successive cards are read concurrently at brushes UB and LB respectively (Fig. 1) and the detection of a card perforation at e.g. the lower brushes LB completes a circuit from wire 335, card lever contacts 59, contactbreakers 61, contacts L11B, through the reading brushes LB and plug board connections 316 to energize the pick-up coil 359 of the " B " relay (see also Fig. 2) for the appropriate denomination. The circuits for the upper brushes UB and the " A " relays are similar and where both A and B pick-up coils 359 are energized concurrently there will be no change in the positions of the armatures 365, 372. However, if e.g. the pick-up coil 359 of the " A " relay is energized first, the armature 365 is rocked clockwise, closing contacts A2, A3 and opening contacts A1. The closing of contacts A3 sets up a holding circuit for the holding winding 360 of the " A " relay so that subsequent energization of the pick-up coil 359 of the " B " relay is ineffective to attract the armatures 365, 372. The prior energization of the " A " relay in this manner breaks the circuits of relays 366, 370 and initiates a total-taking operation if the cards are arranged in ascending sequence and a switch S is therefore in its " A " position. Where a card is out of sequence, however, a " B " relay is energized and total-taking is inhibited. In this case a relay 380 is energized which, by opening contacts 380b, stops the machine. An indicator lamp 384 is illuminated. The circuit provides for superior control by a higher denomination when a digit changes from 9 to 0 in the normal sequence.
